[ 5 7 ABSTRACT The manually operable roller type printing device has a body frame adapted to be slidably moved on the surface to be printed, and the body frame mounts therein a rotatable printing roller movable toward and away from the surface to be printed and urged normally away from the surface to be printed, a rotatable ink applying roller rotatably contacting with the printing roller for supplying ink to the printing roller, an ink distributing pad contacting with the ink applying roller for uniformly distributing ink on the peripheral surface of the ink applying roller as it rotates, and a manually operable pressing lever operably coupled with the printing roller so as to move the printing roller toward the surface to be printed by the actuation of the pressing lever. The printing device is provided with a coupling member operably coupling the movement of the printing roller with each of the ink applying roller and the ink distributing pad, so that the ink applying roller is moved apart from the printing roller and the ink distributing pad is moved apart from the ink applying roller when the printing roller is moved away from the surface to be printed.

Heretofore, in the prior art manually operable printing device of theroller type, uneven printing cannot be avoided when the device is used after it is kept in its inoperative position. In other words, when the operation of the printing device is interrupted, the printing roller is left to be in contact with the ink applying roller and the ink distributing pad is also kept in contact with the ink applying roller, or theprinting roller is kept in contact with the surface to be printed, so that the ink is held in the contacting portions so as to be dried and solidified, thereby resulting in uneven printing in the next operation of the printing device.

Such a shortage takes place even in a short time period when an ink for the drawing or drafting is used which has a high viscosity and is easily dried. Further, when the ink applying roller is made of a material such as a hard rubber, a deformation will take place in the ink applying roller due to the contacting pressure applied thereto thereby requiring a relatively long time to restore its regular form so as to be ready for the next operation, or the ink applying roller is subjected to a permanent set of the deformation thereby resulting in uneven printing due to the non-uniform supply of the ink because of the deformed ink applying roller. Particularly, when the printing operation is effected to make a thin line, a dotted line or a dot-like figure in the relief printing operation, uneven printing will easily result, because a local deformation ofthe ink applying roller tends to occur.

On the other hand, when the printing roller is kept in I contact with the surface to be printed during the time the printing device is inoperative, the ink held in the contacting portions is excessively absorbed in the surface to be printed thereby reducing the amount of the ink held on the peripheral surface of the printing roller at the contacting portions in comparison with the amount of the ink applied to the remaining portion of the printing roller so that uneven printing cannot be avoided in the next printing operation even though the ink is evenly applied appropriately from the ink applying roller to the peripheral surface of the printing roller during the printing operation, because the reduced amount of the ink at the above described contacting portions of the printing roller will not vary for some time at the beginning of the operation. Such a shortage can occur even through the printing roller is kept in contact with the surface to be printed for relatively short time.

SUMMARY OF THE INVENTION lt is an object of the present invention to provide a novel and useful manually operable printing device which avoids the above described disadvantages of the prior art. The printing device of the present invention has a body frame, a printing roller rotatably supported on a printing roller holding lever which is swingably supported in the body frame so as to permit the printing 0 roller to be moved toward and away from its operative position for printing, an ink applying roller rotatably supported on an ink applying roller holding member which is swingably supported in the body frame so as to move the ink applying roller into contact with an away from the printing roller, a first spring operably coupling the printing roller holding lever with the body frame so as to move the printing roller away from the operative position for printing, a second spring with its ends connected to the body frame and the ink applying roller holding member so as to urge the ink applying roller against the printing roller, an ink distributing pad sup ported on a pad holding lever which is swingably supported on the ink applying roller holding member and resiliently urged against the ink applying roller by a spring, and a manually operable pressing lever operably coupled with the printing roller holding lever so that the printing roller is moved toward its operative position for printing againstthe action of the first spring upon actuation of the pressing lever, the printing device comprising a coupling or upstanding member secured to the printing roller holding lever, the up standing member being so operably coupled with each of the ink applying roller holding member and the pad holding lever that, when the pressing lever is actuated, the upstanding member is disengaged from each of the ink applying roller holding member and the pad holding lever so as to move the ink applying roller and the ink distributing pad into contact with the printing roller and the ink applying roller, respectively, while the ink applying roller and the ink distributing pad are moved apart from the printing roller and the ink applying roller, respectively, by the engagement of the upstanding member with each of the ink applying roller holding member and the pad holding lever, when the printing roller holding lever is moved by the action of the first spring so as to move the printing roller apart from its operative position for printing.

Thus, the ink applying roller and the ink distributing pad are held spaced apart from the printing roller and the ink applying roller, respectively, insofar as the printing device is inoperative in which the printing roller is moved apart from the surface to be printed. Therefore, the uneven local solidification of the ink on the contacting portions of the rollers and the pad is positively prevented, thereby insuring uniform printing in the next printing operation.

In accordance with one feature of the present invention, the first spring is directly connected between the printing roller holding lever and the body frame so as to urge the printing roller apart from the surface to be printed, and the printing roller is moved to its operative position through the manual force for operating the pressing lever. An intermediate lever may or may not be provided which operatively couples the manually operable pressing lever with the lever.

printing roller holding In accordance with another feature of he present invention, an intermediate lever is provided which operatively couples the manually operable pressing lever with the printing roller holding lever, and a third spring is provided which has its ends connected to the body frame and the printing roller holding lever, respective ly, so as to urge the printing roller to its operative position for printing, one end of the first spring being connected to the intermediate lever while the other end is connected to the body frame so as to urge the printing roller away from the operative position, the third spring being selected to be weaker than the first spring so that the printing roller is normally held apart from its operative position for printing, thereby permitting the printing roller to be urged to its operative position by the action of the third spring upon actuation of the pressing lever.

Therefore, constant printing pressure of the printing roller is insured by the third spring regardless of the manual force for actuating the pressing lever.

DETAILED DESCRIPTION or THE PREFERRED EMBODIMENTS Referring .to FIGS. 1 and 2, the first embodiment of the printing device of the present invention comprises a body 'frame l in the U-shape in crosssec'tion. A base plate 1' is secured to the lowerend of the body frame 1. A cover 2 and a ruler plate 3 are secured to the base plate 1 as shown. The cover 2 serves to move the printing device for the printing operation by grasping the cover 2 by the handof the operator while the ruler plate 3 serves to guide the movement of the printing device on the surface 6 to be printed as described later.v

A pair of parallel raised edges 4,5 are formed on the lower surface of the ruler plate 3 at the opposite sides thereof, which facilitate the sliding movement of the ruler plate 3 on the surface6 to be printed. The side surfaces 7 of the ruler plate 3 are made perpendicular to the surface 6 to be printed and parallel to the raised edges 4,550 as to facilitate the guiding of the printing device .along the straight line in cooperation with a ruler placed on thesurface 6 to be printed.

A shift 8 is mounted on the body frame 1 in parallel to the surface 6 to be printed and perpendicular to the side surfaces 7, and an ink applying roller holding member 9 is swingably mounted on the shaft 8. A shaft l0'is secured to the forward end portion of the ink applying roller holding member 9 on the side surface thereof on which an ink applying roller 11 is rotatably mounted. The ink applying roller 11 may be interchangeable and the purpose of the roller 11 will be described later. The tail portion 22 extending rearwardly from the holding member 9 serves as a stopper abutting against the base plate 1' when the holding member 9 rotates in the clockwise direction A as seen in FIG. 2. One end of a tension spring 21 is secured to the base plate 1' while the other end is secured to the holding member 9 so that the same is urged in the anticlockwise direction as seen in FIG. 1.

A shaft 12 is secured to the holding member 9 and an ink container holding lever 14 is swingably mounted on the shaft 12. An ink container 13 is detachably attached to the lever 14 so that the ink supplying tip 15 of the ink container 13 contacts with the peripheral surface of the ink applying roller 11 by the gravity of the container 13 or the action of a spring (not shown) thereby permitting the ink to be supplied on the peripheral surface of the roller 11. When the supply of ink is not desired, the lever 14 may be swung in the anticlockwise direction in FIG. 1 so as to disconnect the tip 15 of the container 13 from the roller 11. In this position, the container 13 may be easily exchanged.

A bearing 16 is secured to the ink applying roller holding member 9 as seen in FIGS. 1 and 2, and a shaft 17 is rotatably supported in the bearing 16. The proximal end of an ink distributing pad holding lever 19 is secured to one end of the shaft 17 while the distal end supports thereon a sponge-like ink distributing pad 18. A spring 20 secured at its one end to the holding member 9'and its other end to the lever 19 urges the lever 19 in the direction opposite to that indicated by E in FIG. 1, i.e., in the clockwise direction, so as to resiliently urge the pad 18 against the peripheral surface of the roller 11. v

A knob 17' is secured to the other end of the shaft 17 as seen in FIG. 3 so that the lever 19 may be rotated in the direction E beyond the dead point of the action of the spring 20 by the operation of the knob 17 thereby permitting the pad 18 to be held apart from the roller 11. A radially extending arm (not shown) is formed on the knob 17 and an adjusting screw (not shown) mounted on the holding member 9 is adapted toabut against the arm, so that the position of the pad 18 relative to the peripheral surface of the roller 11 is adjusted by the adjusting screw for appropriately adjusting the pressing for of the pad 18 against the peripheral surface of the roller 11. I

A, printing roller holding lever 24 is swingably mounted on the base plate 1' by a shaft 23 secured to the base plate 1. The free end portion of the lever 24 is formed with 'a through hole and a printing roller'26 having a center shaft 25 may be interchangeably and rotatably mounted on the lever 24 by fitting the shaft 25 within the through hole of the lever 24. A swingable stopper lever (not shown) is provided on the lever 24, which releasably engages with the annular groove formed in the shaft 25 so as to prevent the axial movement of the shaft 25 for the proper axial positioning of the printing roller 26.

The position of the ink applying roller 11 relative to the printing roller 26 is so determined that the roller 1 1 is moved to contact with the roller 26 or away from the roller 26 as the holding member 9 is swung in the anticlockwise or clockwise direction.

Various configurations may be formed in the peripheral surface of the printing roller so that not only a straight line but also a dotted line, a broken line, a chain line or any desired shape may be printed by interchanging the printing roller having the desired peripheral configuration.

A mounting member 27 having an upstanding member 28 and an inclined member 31 is secured to the lever 24 and one end of a tension spring 32 is secured to the free end of the inclined member 31 while the other end is secured to the base plate 1'. Thus, the printing roller holding lever 24 is normally urged in the direction B by the action of the spring 32.

A manually operable pressing lever 36 having a manually operable lug 35 is pivotally mountedin the body frame 1 by a shaft 33 secured to the body frame 1. The lever 36 has a bent lug 36a formed near the pivoted end thereof, One end 37a of an intermediate lever 37 swingably mounted in the body frame 1 at its intermediate portion by a shaft 34 is adapted to abut against the bent lug 36a, while the other end 37b abuts against the lower side of the inclined member 31. Thus, the intermediate lever 37 is urged in the anticlockwise direction by the action of the spring 32 urging the inclined member 31 downwardly, so that the pressing lever 36 is urged upwardly, lie. in the clockwise direction, by the abutment of the bent lug 36a against the end 37a of the intermediate lever 37. When the pressing lever 36 is manually pressed downwardly by urging the lug 35 by the finger of the operator, the inclined member 31 and, hence, the printing roller holding lever 24 are swung in the anticlockwise direction against the action of the spring 32 by the interposition of the intermediate lever 37, so that the printing roller 26 is moved to contact wit-h the surface 6 for the printing operation.

An adjusting screw (not shown) may be provided in the end 37a which abuts against the lug 36a of the pressing lever 36 so that the relative position of the end 37a of the lever 37 with respect to the lug 3611 can be adjusted appropriately.

In accordance with the characteristic feature of the present invention, the upstanding member 28 secured to the printing roller holding lever 24 is operably coupled with the bearing 16 secured to the ink applying roller holding member 9. The spring 32 urging the lever 24 and, hence, the upstanding member 28 in the clockwise direction B is made stronger than the spring 21 urging the holding member 9 in the anticlockwise direction so that the,h0lding member 9 is normally urged in the clockwise direction A until the tail 22 abuts against the base plate 1 by the action of the spring 32 against the action of the spring 21 by virtue of the engagement of the bearing 16 with the upstanding member 28, thereby moving the ink applying roller 11 apart from the printing roller 26.

Further, a pin is secured to the upper portion of the upstanding member 28, and the pin 30 is operably coupled with the pad holding lever 19 so that the lever 19 is swung in the anticlockwise direction to move the pad 18 part from the ink applying roller 11 when the holding member 9 is swung in the clockwise direction as shown in FIG. 2.

When the pressing lever 36 is manually pressed downwardly, the printing roller holding lever 24 is swung in the anticlockwise direction to bring the printing roller 26 to its operative position for printing and, at the same time, the upstanding member 28 and the pin 30 are disengaged from the bearing 16 and the pad holding lever 19, respectively, by the anticlockwise swinging movement of the lever 24, so that the ink roller holding member 9 is swung in the anticlockwise direction by the action of the spring 21 to bring the ink applying roller 11 into contact with the printing roller 26 while the pad holding lever 19 is swung in the clockwise direction to bring the pad 18 into contact with the ink applying roller 11.

In operation, the pressing lever 36 is previously pressed downwardly so as to bring the printing roller 26 and the ink applying roller 11, and the pad 18 and the ink applying roller 11 into contact with each other, respectively, and the printing roller 26 is rotated so as to supply the ink from the container 13 to the peripheral surface of the printing roller 26 through the ink applying roller 11, and the adjusting screw for adjusting the pressing force of the pad 18 against the ink applying roller 11 is adjusted to set an appropriate pres sure of the pad 18, and the printing device is placed on the surface 6 to be printed at a desired position and in the desired direction for the printing operation. A ruler may be placed along one of the sides 7 of the ruler plate 3 for slidingly guiding the printing device along the ruler.

When the printing operation is to be commenced, the pressing lever 36 is pressed downwardly by the finger of the operator and the printing device is moved leftward in FIG. 1 by grasping the cover by the hand of the operator. By the operation of the lever 36, the printing roller 26 is moved to contact with the surface 6 to be printed and, at the same time, the ink applying roller 11 contacts with the printing roller 26 while the pad 18 is urged against the ink applying roller 11, the tip 15 of the ink container 13 being in contact with the ink applying roller 11 for supplying ink to the ink applying rollcr 11. When the printing device is moved on the surface 6 with the pressing lever 36 held pressed downwardly, the printing roller 26 contacting the surface 6 rotates in the direction C to effect the printing on the surface 6 and the ink applying roller 11 contacting with the printing roller 26 is also rotated so as to successively supply ink to the printing roller 26. The pad 18 urgingly contacting with the: ink applying roller 11 serves to uniformly distribute the ink over the peripheral surface of the ink applying roller 11 so that the amount of the ink successively supplied to the peripheral surface of the printing roller 26 is made uniform thereby insuring the uniform printing to be effected on the surface 6.

When the pressing lever 36 is released after the desired printing is obtained, the printing roller holding lever 24 is swung upwardly so that the printing roller 26 is moved apart from the surface 6 and, at the same time, the ink applying roller 11 is moved apart from the printing roller 26 while the pad 18 is moved apart from the roller 11 as previously described, so that the solidification of the excessive amount of the ink in the portions of the rollers 26, 11 and the pad 18 contacting with each other is positively prevented. Thus uneven printing is positively avoided in the next printing operation.

FIGS. 4 and 5 show the second embodiment of the printing device of the present invention. This embodiment is substantially similar in construction and operation to that shown in FIGS. 1 to 3 except that the printing roller 26 is urged against the surface 6 by the action of an additional spring 132 upon actuation of the pressing lever 36 instead of urging the printing roller 26 by the manual force operating the pressing lever 36 as in the case of the embodiment shown in FIGS. 1 to 3, so that a constant printing pressure is given to the printing roller 26 regardless of the variation in the manual force actuating the pressing lever 36.

In the embodiment shown in FIGS. 4 and 5, a pin l37b is secured to one end of the intermediate lever 137 which is similar to the intermediate lever 37 of FIGS. 1 to 3 adjacent to inclined member 31 secured to the printing roller holding lever 24 and the pin abuts against the upper side of the inclined member 31. One end of the tension spring 138 which is similar to the spring 38 of FIGS. 1 to 3 is connected to the intermediate lever l-37 adjacent to the pin l37b and the other end is secured to the base plate 1 so that the intermediate lever 137 is urged in the anticlockwise direction. Thus, the inclined member 31 and, hence, the printing roller holding lever 24 are urged in the clockwise direction by the engagement of the inclined member 31 with the pin l37b of the intermediate lever 137 as in the case of the embodiment shown in FIGS. 1 to 3. The end 137a of the lever 137 is provided with an adjusting screw 1370 which abuts against the lug 36a of the pressing lever 36.

One end of an additional spring 132 is connected to the free end of the inclined member 31 while the other endis connected to a pin 132a secured to the body frame 1 at a position higher than the free end of the inclined member 31 so that the inclined member 31 and, hence, the printing roller holding lever 24 is urged by the spring 132 in the anticlockwise direction thereby urging the printing roller 26 against the surface 6 to be printed by the action of the spring 132.

The spring 138 is selected to be stronger than the spring 132 so that the inclined member 31 and, hence, the printing roller holding lever 24 is normally urged in the clockwise direction by the action of the spring 138 against the action of the spring 132. Thus, the printing roller 26 is normally held apart from the operative position for printing.

In operation, when the pressing lever 36 is pressed downwardly, the intermediate lever 137 is rotated in the clockwise direction against the action of the spring 138. THus, the printing roller holding lever 24 is swung in the anticlockwise direction by the action of the spring 132 thereby urging the printing roller 26 against the surface 6 for the printing operation by the force of the spring 132 regardless of the manual force actuating the pressing lever 36.

Therefore, uniform printing force is insured by the spring 132.

In the embodiments described above, the ruler plate 3 is shown as being secured to the base plate 1' by set screws. However, the ruler plate may be integrally formed together with the base plate. Also, the printing roller holding lever 24 may be provided with a shaft instead of a through hole and the printing roller having a central through hole instead of a center shaft may be rotatably and interchangeably fitted on the shaft secured to the lever 24.
